BS10 Slip On Bossed Flanges

Our BS10 slip on bossed flanges come in tables D, E, F & H as well as sizes between 1/2″ and 12″. These welding flanges come bossed for a stronger weld joint and with a flat sealing face, they’re made of S235JR mild steel. Our BS 10 steel flanges are available with 3.1 test certification. Slip-ons are typically fillet welded to steel fittings or pipework.
